Bug 10866: Hide patron's history if intranetreadinghistory is set to not allow

If set to "not allow", the intranetreadinghistory pref prevent staff
members to access patron's checkout history.
But:
1/ The page is still accessible if you know the url
2/ The history can be consulted on the item history page

Test plan:
0/ Don't apply this patch
1/ Set the intranetreadinghistory to allow
2/ Go on a patron's checkout history page
3/ Open a new tab and go on a item's checkout history page
4/ Set the intranetreadinghistory to not allow
5/ Refresh both pages => no change
6/ Apply this patch
7/ Refresh both page.
On the first page, you should see a warning
On the other one, you should see that the patron column is not displayed
anymore.

Followed test plan, results were as expected.
